HARRY E. DORR, OF ST. LOUIS, MISSOURI, ASSIGNOR T0 SCULLIN STEELCOMPANY,

OF ST. LOUIS, MISSOURI, A CORPORATION OF MISSOURI.

To all whom t may concern:

Be it known that I' HARRY E, Donnn, a`

States, residing at St. Louis, in the county of St. Louis andState ofMissouri, have invented certain new and useful Improvements inPedestal-Truck Side Frames, of which the following is a specication. l

This invention relates to pedestal truck side frames. Heretoforepedestal truck side frames have required Aa special journal box. Accordingly, such a side frame could not be used for replacements of Varchbars or the lstandard type of frame, both of which use Master CarBuilders journal boxes.

Therefore, one object of this invention is to provide a simple and novelpedestal truck side frame which will accommodate Master Car Buildersjournal boxes.

Another object is to provideV a truck side frame which may be detachablyconnected to a journal box in a manner to obviate the use of bolts andwhereby an emergency fastening is formed should the truck be derailed orlifted from the track by any other part than the axles.

These and other objects are accomplished. by means of the arrangementdisclosed on the accompanying sheet of drawings, in which- 7 Figure 1 isa fragmentary side elevation of my improved pedestal truck side frame.showing its means of attachment to a Master Car Builders standardjournal box;

Fig. 2 is a top plan view of the same arrangement; and

'Fig. 3 is an end view thereof.

The-.various novel features of my invention will be apparent from thefollowing description and drawings and will be par ticularly pointed outin the appended claims.

Referring to the figures of the drawings, it will be noted that I haveprovided a truck side frame 10 having pedestal jaws 11, the lower endsof which terminate in laterally extending portions 12, which extendtoward' each other lengthwise of the side frame. These extendin jawportions 12 engage thev sides of the astcr Car Builders journal box 13intermediate its ends, and more particularly intermediate the verticalplanes o the journal box bolt lugs 14. As 1s apparent from thearrangement disclosed in the figures of the drawings, it would be impos-Specication of Letters Patent.

Application mea December 29, 191a serial no. 347,976.

sible to apply the side frame to the journal box by a relative verticalmovement while the jaw extensions 12 are intermediate the journal boxbolt lugs 14. Accordingly, to apply the side frame to the journal boxlwhen the latter is fixed on the journal, the side frame 10 is movedinwardly with respect to the journal box to a point where the relativelynarrow ja'w extensions 12 may pass vertically downwardly between theinner journal box bolt'y lugs 14 and the dust guard housing 1 5. Withthe side frame in this position the same may be'lowered, permitting thejaw extensions 12 to`l pass vertlcally downwardly beyond the upperjournal box bolt lugs 14, whereupon the side .frame may beI movedrelatively outwardly with respect to the journal box totake its normaloperating position. It will benoted that the side frame 10 is rovidedwithvfour housing lugs 16 which t over the outside and embrace the fourupper journal box bolt lugs 14. Accordingly, when the journal box 13 andside frame have been moved relativel laterally to a point where thehousing ug 16 may assume the proper position with respect to the boxlugs 14, the side frame 10`is lowered into the position shown in Fig. 1of the drawings to revent relative lateral movementbetween t e sideframe and journal box under normal operating conditions. It will benoted that the jaw extensions 12 are spaced from the'housing lugs 16.vertically an amount to accommodate the box lugs 14 in applying theframe to and withdrawing the same from` maintaining the connectlonbetween the sideframe and the journal boxes, and therefore the wheelsand axles, in the event that the truck -is derailed or islifted from thetra-ck by any other part than the axles. It will be noted that no boltsor other fastenin s of anykind are required to hold :the'si e frame inproper position other than the parts hereinabove s ecically set forththe housing lugs 16 em racing the sides of the journal box lugs 14 andthe pedestal jaw extensions 12 bearing against the sides of the box Iforholdin the same in proper rerame. It will beunderstood that when it isdesired to replace a by raising the sider frame an amountjvto ing openpedestal jaws havin properly accommodate the upper journal' box lugs 14between the jaw extensions 12 and the housing lugs 16, whereupon'the newjournal box may be moved (laterally inwardly to the point where thehousing lug 16 my move down over the journalbox lll v 5 is my intentionto'cover all modifica vent relative lateral movement between the sideframe and journal box, said jaws terminating in inwardly extendingportions for engaging the sides 4of the boxes for supportv ing same.

2. A pedestal truck side frame including open pedestal jaws havingportions.,whic'h engage bolt lugs-on Master Car Builders journal boxesnormally to prevent lateral movement between the side frame and journalbox, said jaws terminating in inwardly extending portions for engagingsaid bolt lugs to prevent accidental vertical separation of the boxesfrom the frame.

3. A pedestal truck side frame including j race bolt lugs of lateral.movement pedestal jaws having cooperating boxte-i ceiving portionswhich may be applied to a Master Car Builders journal box between theinner lugs on 'the latter and the dust guard housing whereupon the sideframe and journal box may be moved relatively to each other. to theirnormal relative positions. 4. A pedestal truck'side frame includingpedestal jaws havinguportions which emaster Car Builders boxes normallyto ,prevent relative between the -side frame and journal box, saidpedestal jaws also having .portions which embrace the sides of thejournal box between the bolt lugs thereof for assisting .in maintainingthe operative position of said side frame and said journal journal box.

, 5. A pedestal truck side frame havingl open pedestal jaws and lugsspaced from each other whereby. a journal vbox having lugs may beapplied by a lateral movement therebetween, said pedestal yjaws normallyembracing the sides of the journal box and- .I said lugs embracing thejournal box lugs for preventing relative movement betweenthe side frameand journal box.'-
